Measured on your wrist.

SlalomSurfingPRO turns your Garmin watch into a windsurf and slalom computer: GPS-Speedsurfing values, automatic jibe and tack analysis, and a race-start countdown, live on the water.

What it does

Built by a slalom sailor, for the water.

Big, high-contrast numbers you can read at arm's length in the sun. Everything is recorded to your Garmin activity, and the last 10 sessions stay on the watch.

GPS-Speedsurfing values

Max, 2 s, 10 s, 5×10, 250 m, 500 m, alpha 500, 1 h and 2 h, computed live from Doppler speed. Top 5 separate runs for each value.

Jibe & tack analysis

Turns are detected automatically and classified as jibe or tack from an estimated wind axis. Entry, minimum and exit speed, speed kept and recovery time for every turn.

Turn statistics

Jibes and tacks side by side, split left and right, so you see your strong and your weak side. Your best jibe and best tack, shown on the map.

Race-start countdown

Configurable countdown with sync to the full minute, vibration at every minute and in the last seconds, and the start marked in your activity.

Alerts & auto-pause

Vibration when you beat your best or pass a speed you choose. Auto-pause when you stop, so waiting on the beach never spoils your averages.

Results on the watch

View the results of your last 10 sessions right on the watch. Every turn is a lap in the saved activity, so Garmin Connect shows the full turn table.

FAQ

Questions

How do I install it?

Open the Connect IQ Store app on your phone, search for “SlalomSurfingPRO”, and install it on your watch. Start it from the watch's app list.

Does it replace the Garmin windsurf activity?

Yes. It records a normal Garmin windsurfing activity (GPS, heart rate, laps) and adds its own values, so everything syncs to Garmin Connect as usual.

How does it tell a jibe from a tack?

It learns the wind axis from how you sail back and forth. Until the wind is known a turn is shown as “turn”; it is re-classified as soon as the wind estimate is confident.

What happens when the beta ends?

The beta no longer starts new recordings after 30 November 2026. Activities already in Garmin Connect and results saved on the watch are not affected.
